Earth Hour is an annual, international event that unites people to protect our beautiful planet.  Find out more from the organization's site: www.earthhour.org

We'll turn off as many lights as possible around the museum to get the best view of the sky from our observatory and other telescopes provided by the Albuquerque Astronomical Society (weather permitting).

In the museum, learn about the environment, conservation, and recycling from these displays and activities:

• At 8, 8:30 & 9 p.m., the short planetarium show "Losing the Dark" will show how light pollution affects public safety, nocturnal animals, and our view of the universe.
• The City of Albuquerque Recycling Program will have information about what to put in your blue bins and what to keep out.
• Hawks Aloft is bringing live owls to show how they are adapted for hunting in the dark.
• The Naturalist Center will have other animals which only come out at night and information on how light pollution can actually be deadly to some species (closes at 9 p.m.).
• The Degrees of Change exhibit will be open with information about many forms of pollution.
• Enjoy fun activities which also teach how to be good stewards of our home, the Earth.
• Watch a live feed of other Earth Hour celebrations around the world.
